Collaborate Disseminate
Field-programmable gate arrays (FPGAs) are, so to say, a computer manufacturer’s “Lego bricks”: electronic components that can be employed in a more flexible way than other computer chips. Even large data centers that are dedicated to… Continue reading Scientists uncover vulnerability in FPGAs, affecting cloud services and IoT
There can be few of us who haven’t gazed with fascination upon the work of IC decappers, whether they are showing us classic devices from the early years of mass semiconductor manufacture, or reverse-engineering the latest and greatest. But so often their work appears to require some hardcore scientific equipment …read more
A new computer processor architecture that could usher in a future where computers proactively defend against threats, rendering the current electronic security model of bugs and patches obsolete, has been developed at the University of Michigan. Calle… Continue reading Unhackable? New chip makes the computer an unsolvable puzzle
A vulnerability in Qualcomm chips could be exploited by attackers to retrieve encryption keys and sensitive information from the chipsets’ secure execution environment, NCC Group researchers have found. About CVE-2018-11976 The security of Truste… Continue reading Qualcomm chips leak crypto data from secure execution environment
In early 2018, cybersecurity researchers discovered two security flaws they said were present in almost every high-end processor made and used by major companies. UPEC product development team (l to r): Mo Fadiheh, Wolfgang Kunz, Dominik Stoffel. Known… Continue reading Algorithms can now find bugs in computer chips before they are made
Not every computer is a performance gaming rig. Some of us need cheap laptops and tablets for simple Internet browsing or word processing, and we don’t need to shell out thousands of dollars just for that. With a cheaper price tag comes cheaper hardware, though, such as the eMMC standard which allows flash memory to be used in a more cost-advantageous way than SSDs. For a look at some the finer points of eMMC chips, we’ll turn to [Jason]’s latest project.
[Jason] had a few damaged eMMC storage chips and wanted to try to repair them. The most common failure …read more
A vulnerability in the firmware of a Wi-Fi chipset that is widely used in laptops, streaming, gaming and a variety of “smart” devices can be exploited to compromise them without user interaction. The research and the discovered flaws The di… Continue reading Bug in widespread Wi-Fi chipset firmware can lead to zero-click code execution
Building an LED matrix is a fun project, but it can be a bit of a pain. Usually it starts with hand-soldering individual LEDs and resistors together, then hooking them up to rows and columns so they can be driven by a microcontroller of some sort. That’s a lot of tedious work, but you can order an LED matrix pre-built to save some time and headache. You’ll still need a driver though, and while building one yourself can be rewarding there are many pitfalls and trade-offs to consider when undertaking that project as well. Or, you can consider one of …read more
“Gummy” might not be an adjective that springs to mind when describing metals, but anyone who has had the flutes of a drill bit or end mill jammed with aluminum will tell you that certain metals do indeed behave in unhelpful ways. But a new research paper seeks to shed light on the gummy metal phenomenon, and may just have machinists stocking up on office supplies.
It’s a bit counterintuitive that harder metals like steel are often easier to cut than softer metals; especially aluminum but also copper, nickel alloys, and some stainless steel alloys. But it happens, and [Srinivasan …read more

Sixty years ago this month, an unassuming but gifted engineer sitting in a lonely lab at Texas Instruments penned a few lines in his notebook about his ideas for building complete circuits on a single slab of semiconductor. He had no way of knowing if his idea would even work; the idea that it would become one of the key technologies of the 20th century that would rapidly change everything about the world would have seemed like a fantasy to him.
We’ve covered the story of how the integrated circuit came to be, and the ensuing patent battle that would …read more
